braze type refrigerant connections for easy installation. If a

TXV is not installed but required for your application, see

Table 1 to determine the proper kit based on tonnage and

refrigerant type of the unit.

• Check the coils oriﬁce size and conﬁrm that it’s suitable

for application with the intended outdoor unit. Depending

on application, additional installer supplied oriﬁce or TXV

may be required.

• Optional cooling/heating equipment must be properly sized

and installed in accordance with the furnace manufacturer’s

speciﬁcations and approved recommendations.

• Heating only furnace air circulators may have to be replaced

with multi-speed heating / cooling blowers to upgrade the

air delivery (CFM) when an add-on coil is installed. Refer

Table 3, Table 4, or Table 5, (page 7) for coil

speciﬁcations, recommended CFM, and allowances for

pressure drop across the coil and ﬁlters.

• Verify that the air delivery of the furnace/air handler is

adequate to handle the static pressure drop of the coil,

ﬁlter, and duct work.

• If precise forming of refrigerant lines is required, a copper

tubing bender is recommended. Avoid sharp bends and

contact of the refrigerant lines with metal surfaces.

• Refrigerant lines should be wrapped with pressure sensitive

neoprene or other suitable material where they pass against

sharply edged sheet metal.

• Horizontal installations require a horizontal drain pan kit to

be installed. See

Table 3, Table 4, or Table 5 for available

part numbers.

NOTE: The holes in the drain pan extension should be

pressed over the nibs molded into the drain pan. Which

pair of holes to use will depend on whether the unit is

installed horizontal left or horizontal right. Verify proper

positioning for clearance thru the top of the coil cabinet

before afﬁxing. The drain pan extension can be installed

and removed after the ductwork has been attached to the

cased coil.

Condensate Drain

CAUTION:

The coil must be level to ensure proper condensate

drainage. Improper condensate disposal may result

in structural damage, premature equipment failure,

or possible personal injury.

• Methods for disposing of condensate vary according

to local codes. Refer to local codes or authority having

jurisidiction for restrictions and proper condensate disposal

requirements.

• All condensate pans have primary and secondary drain

connections to meet FHA requirements. If the application

is located in or above a living space where damage may

result from condensate overﬂow, a separate 3/4 inch drain

must be provided from the secondary drain connection and

a secondary drain pan must be installed under the entire

unit. Run secondary drain lines to a place where they are

noticeable if used.

• The coil condensate pan is designed with 3/4” NPSC drain

connections. Use a PVC or similar material ﬁtting to attach

the drain line to the pan. NOTE: The ﬁtting should be hand

tightened only. Overtightening may crack the drain pan

and cause condensate to leak.

• The drain pan MUST be drained with ﬁeld supplied tubing

or PVC pipe and adequately trapped.

IMPORTANT NOTE:

Failure to install a trap may result in condensation

overﬂowing the drain pan, resulting in substantial

water damage to surrounding area.

• Prime the trap with water. Insulate the drain if it is located

in an unconditioned space, and test the condensate line

for leaks. Consult local codes for additional restrictions or

precautions.

• Route the lines to a suitable drain, avoiding sharp bends

and pinching of the lines. The drain should maintain a

minimum horizontal slope in the direction of discharge of

no less than 1” vertical for every 10 ft of horizontal run.

• During system checkout, inspect the drain line and

connections to verify proper condensate drainage.

Air Filter

Air ﬁlters are not supplied as an integral part of this coil;

however, an air ﬁlter kit is available. Refer to the Replacement

Parts List for available part numbers.

The ﬁlter must be installed upstream of the coil and inspected

frequently. When the ﬁlter becomes clogged with dust or

lint, it should be replaced (disposable type) or cleaned

(washable type). It is recommended that ﬁlters be inspected

and replaced at least twice during the year. Generally it is

best to replace or clean the ﬁlters at the start of each heating

and cooling season.
